Felix Brown and his brother Adolphus have been practical inventors of machinery. They brought many improvements to existing technologies. For example they succeeded in building an oscillating steam engine.
Felix Brown must not be confused with Samuel Brown, an English engineer and inventor known as the "father of the gas engine" for developing one of the earliest example of an internal combustion engine during the early 19th century.
In 1877 Felix Brown patented a much improved caloric engine that pushed the practical size limit from 6 HP to 14 HP.
It has been his sole known air engine. But it was quite famous at that time.
